How to Make Flank Steak in the Slow Cooker
Step 1 – In a small bowl, whisk together the beef broth, soy sauce, Worcestershire sauce, olive oil, brown sugar, minced garlic, onion powder, smoked paprika, salt, and pepper to create the marinade.
Step 2 – Place the flank steak in the slow cooker. Pour the marinade over the flank steak, making sure it’s evenly coated.
Step 3 – Cover the slow cooker and cook on low for 6-8 hours, until the flank steak is tender.
Step 4 – Once done, remove the flank steak from the slow cooker and let it rest on a cutting board for 5-10 minutes. Slice the flank steak against the grain into thin strips.
Expert Tips
- Cook on High – If you prefer, you can cook on HIGH for 3-4 hours, but the meat won’t be as tender.
- Sauce – If you want a thicker sauce, just create a slurry. Remove the flank steak from the slow cooker once it’s done cooking, and then whisk together 2 tablespoons of cornstarch with 2 tablespoons of cold water. Stir this mixture into the slow cooker and cook on high for an additional 15-20 minutes, or until the sauce has thickened.
- Cutting Flank Steak – After the flank steak has rested, cut the lean cut of beef with a sharp knife on a cutting board against the grain. We like to slice in thin strips to easily serve.
